A species with a broad distribution rarely has the same genetic makeup over its entire range. For example, individuals in a population living at one end of the range may live at a higher altitude ...

A second example of how chemical environments affect gene expression is the case of supplemental oxygen administration causing blindness in premature infants (Silverman, 2004). In the 1940s ...

Researchers hope the AI tool will aid in the development of cell-specific gene therapies to treat diseases such as cancer.
